129,000–226,000. On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days ...

In the PNE Treaty, the signatories agreed: not to carry out any individual nuclear explosions having a yield exceeding 150 kilotons TNT equivalent; not to carry out any group explosion (consisting of a number of individual explosions) having an aggregate yield exceeding 1,500 kilotons; and not to carry out any group explosion having an aggregate yi...
Operation Plowshare was the name of the U.S. program for the development of techniques to use nuclear explosives for peaceful purposes. The name was coined in 1961, taken from Micah 4:3 ("And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks: nation ...
The Soviet Union conducted a much more vigorous program of 239 nuclear tests, some with multiple devices, between 1965 and 1988 under the auspices of Program No. 6—Employment of Nuclear Explosive Technologies in the Interests of National Economy and Program No. 7—Nuclear Explosions for the National Economy. The initial program was patterned on the ...
Germany at one time considered manufacturing nuclear explosives for civil engineering purposes. In the early 1970s a feasibility study was conducted for a project to build a canal from the Mediterranean Sea to the Qattara Depression in the Western Desert of Egyptusing nuclear demolition. This project proposed to use 213 devices, with yields of 1 to...
Apart from their use as weapons, nuclear explosives have been tested and used, in a similar manner to chemical high explosives, for various non-military uses. These have included large-scale earth moving, isotope production and the stimulation and closing-off of the flow of natural gas. At the peak of the Atomic Age, the United States initiated Ope...
The discovery and synthesis of new chemical elements by nuclear transmutation, and their production in the necessary quantities to allow study of their properties, was carried out in nuclear explosive device testing. For example, the discovery of the short-lived einsteinium and fermium, both created under the intense neutron flux environment within...
A proposed means of averting an asteroid impacting with Earth, assuming short lead times between detection and Earth impact, is to detonate one, or a series, of nuclear explosive devices, on, in, or in a stand-off proximity orientation with the asteroid, with the latter method occurring far enough away from the incoming threat to prevent the potent...

7 July 2005 London bombings. The 7 July 2005 London bombings, also referred to as 7/7, were a series of four coordinated suicide attacks carried out by Islamist terrorists that targeted commuters travelling on London's public transport during the morning rush hour.
Tsar Bomba. The Tsar Bomba (Russian: Царь-бомба, romanized: Tsar'-bomba, IPA: [t͡sarʲ ˈbombə], lit. ' Tsar bomb'; code name: Ivan [5] or Vanya ), also known by the alphanumerical designation " AN602 ", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested.
